After eight of nine states on Tuesday voted to pass cannabis legalization initiatives, murmurs are bubbling up from sports media that NFL owners are now privately supporting the idea of making medical cannabis available to NFL players.

More than 60 million new people woke up after Tuesday’s election in a state where adult use cannabis is legal, and 28 states now have medical marijuana laws on the books—meaning legalization is no longer the exception; it’s the rule. The newly legal states include California, Massachusetts, and, for medical use, Florida, all of which are home to NFL teams.

In the past few years, more and more players and commentators have advocated for players to have the option of using cannabis for medical use, noting it could serve as an alternative to prescription painkillers.

The current collective bargaining agreement between the league and the players’ union runs through 2020. Two sides review the sport’s drug policies annually, however, and sometimes make adjustments. In 2014, the league and players’ union together agreed to raise the threshold for what constitutes a failed drug test for cannabis, lifting the limit from 15 nanograms per milliliter to 35 ng/ml.

An NFL drug test that comes back positive for cannabis can carry a wide variety of punishments. While the first violation typically results in a player being referred to a substance abuse program, further violations can result in a four-game suspension without pay.
